Ethylene glycol has a specific heat of 0. 578 cal/(g°c). If 23.2 g of ethylene glycol absorbs 75.6 cal of heat energy. The temperature increase be 5.64°C.
The amount of heat needed to raise the temperature of 1 kg of substance.
It is expressed as
Q = mcΔT
where,
Q = Heat energy
m = Mass
c = Specific heat capacity
ΔT = Change in temperature.
Here,
Q = 75.6 cal
m = 23.3 g
c = 578 cal/(g°c)
Now put the values in above formula we get
Q = mcΔT
75.6 cal = 23.2 g × 578 cal/(g°c) × ΔT
ΔT = 5.64°C
Thus from the above conclusion we can say that Ethylene glycol has a specific heat of 0. 578 cal/(g°c). If 23.2 g of ethylene glycol absorbs 75.6 cal of heat energy. The temperature increase be 5.64°C.
